Letters Patent No 91,538, dated June 22, 1869.

` IMPROVEMENTJN CARRIAGE-SPRINGS.

m um- The Schedule referred to in these Letters Patent and making part0f tu@ im To all whom t may concern:

Be it known that We, EPHRAIM C. HODGE, of' the town of Oneonta, in thecounty of Otsego, and DELos H. MANN, of the town of Delhi, in the countyof Delaware, both in the State of New York, have invented certain newand useful Improvements in Wooden Springs for Wheeled Vehicles; andwe dohereby declare that the following is a full and exact descriptionthereof', reference being had to the accompanying drawings, and to theletters ofreference markedthereon, making a part of this specification,in which- Figure 1 is a perspective view of our invention, as

combined for use.

Figure 2 is a transverse section of the cross-piece F, which connectsthe springs O, and on which the springs D rest, said section showin gtherolling-j cin t, and method `of attaching the springs D to thecross-piece F.

Figure 3 shows another method of attaching the springs D to thecross-pieces F, the rolling, or hingejoint being entirely of metal.

Like letters of reference indicate like parts.

The nature of our invention consists in combining a series of woodensprings with thg running parts and body of a wheeled vehicle, in such amanner as to produce an easy motion of the body on .the springs, while,at `the same time, the whole combination will be light, durable, andcheap.

To enable others skilled in the art to make and use our invention, wewill proceed to describe more fully its manner of constructionandoperatiou.

A represents two wooden reaches, running parallel with each other, andattached, at. their extremities, to

the axle, in rearfand head-block in front.

B represents two arched*woodenspiings, (or elevating-arches,) restingupon, and attached, at their` extremities, to the wooden reaches A, asshown in hg. 1.

` C represents two wooden springs, running paral- A lel with each other,and Secured, at the middle, or

centre, to the top of the arched springs, or elevating-l pieces B, bymeans of metal clips, or boltsfand con nected, at their extremities, bytwo wooden cross. pieces, F, as shown in tig. 1.

D represen-ts two wooden springs, placed between, and running parallelwith the springs O, ata short distance from them.

The springs D are attached, at their extremities, to the cross-pieces F,by means of arolling, or hinge-like joint, as shown in g. 2, in which Dis the spring, F, the cross-piece, and G, the clip, or portion ofhingestrap, connecting the whole together, in such a manner as to allowa rolling, or hinge-like motion, the use of which is to allow morefreedom of motion to the springs O and D, so that they mayact, to acertain extent, independent 'of each other, and not cramp, which theywould naturally do, were the springs D also secured to the cross-piecesF, in such a manner as to have no motion thereon.

If desired, this rolling joint may be made entirely of metal, andsecured to the cross-piece F and spring D, as shown in g. 3.

The body of the vehicle may be attached to the springs D, by means ofrubber or elliptic steel springs E, or by means of saddle-blocks, placedat the centre; but as such devices are commonly used for connecting thebodies of wheeled vehicles with the running-parts, we make no claim tosuch.

What we claim as our invention, anddesire to secure by Letters Patent,is-

In combination with a wheeled vehicle, the reaches A, arched pieces B,springs' C, cross-pieces F, and springs D, the whole being combined,arranged, and operating, in the manner and for the purposes set forth inthe above specification.
